An operating method of a terminal based on multiple inputs and a portable terminal supporting the same are disclosed. The method comprises the steps of providing a panel to form an acoustic radiator; identifying a position on the panel for mounting a vibration transducer to excite bending waves in the panel; and securing a stiffening member to the panel at the position for mounting the transducer to stiffen the panel locally. Selected playing spaces on the board are assigned predetermined characteristics which alter the play of the game, creating bonus locations and penalty locations. Simultaneously or thereafter besides the liquid also a gaseous substance can be supplied thereby creating at least locally a sharply defined liquid-vapor boundary. The invention also relates to novel 6-alkoxy-2,3-diaminopyridine compounds that are useful as couplers. A memory function implemented by these two charge holding portions and a transistor operation function implemented by the gate insulating film is separated from each other for securing sufficient memory function as well as easily suppressing short channel effect by making the gate insulating film thinner.
